"...where we got it wrong was after the summer break, with the introduction of the new tyres.

From a car that was very aggressive on the rears, we developed the right things to manage the rears, so when the new tyre was introduced probably we over-managed. Our car almost had a Lotus phenomenon afterwards - it was too gentle on the tyres, we could not switch them on, we could not warm them up in the appropriate way.

This is where you decide to take some junctions with the development and sometimes you have to retrace them. It is a difficult process and that is where we have to improve."
